Description

Fire-proof door

Technical Field

The invention relates to a door, in particular to a fireproof door.

Background

In a building, many fireproof escape doors are usually arranged between a safety area and a living area, and the doors are normally closed in a normal state and are rarely opened, so that the fireproof doors cannot be blocked. However, the fire-proof doors have the same problem in case of fire, that is, when the fire-proof doors are opened, the safety area is communicated with the fire-catching area, so that a large amount of smoke is poured into the safety area, the smoke in the safety area is diffused, the fire-proof doors are not beneficial to escape, and the safety hazard is brought to people who can smoothly escape. Furthermore, the ceiling in the area of fire, etc., is randomly dropped and burned, and therefore, there is a certain risk to the escaper passing through the fire door, and the installation position of the fire door is relatively inconspicuous and thus is not easily noticed.

Finally, because the escaper possibly carries flames, the flames are possibly not found by the escaper, and the flames are not extinguished at the moment, the flames are possibly burnt all over the body, even if the escape is successful, a large area of skin burns exist, and the potential safety hazard is large. Meanwhile, the fireproof door is a single-layer or multi-layer door plate, and after the fireproof door is in transition contact with flame, the fireproof door can be damaged, so that the whole safe area can be switched on, and a large amount of smoke is gushed into the fireproof door to bring great potential safety hazards to escape of escapers.
